Comment (by barry.wardell):

 The changes look good to me. I've tested the SSE and default versions and
 they all compile and pass the Vectors testsuite on Damiana, Datura and my
 laptop. They also compile on Scientific Linux 6 which previously caused
 problems for me.

 I didn't test the Altivec, DoubleHummer or VSX changes but they look
 correct. Any errors should be caught by the testsuites, so assuming those
 pass, I think this should be be committed.
